OK, correct there ARE T-Tops in 93. Just very few! It was Vert I must have been thinking.

The 94-97 have a 4L60e (controlled by PCM)
My notes from chatting with Frank @ CPT on the subject:
A 4L60 (no E) is a 700R4. GM just changed the designation for 1993. The '93 F-Body unit has different valve body, spacer plate, and lock-up wiring than any previous 700R4, though. The reverse input housing is also specific to 1993.

I think he's correcting you on the 700R4 bit. While technically it's a 700R4, I suppose now in light of that new info, calling it a 4L60 would be more accurate. Since it has unique parts to that year.

Part of the argument for the 93's being a tad faster than the other LT1 cars is because they had a slightly, and I mean SLIGHTLY larger camshaft. I can't remember where the specs are or else I would post them, but I have seen the comparison.

I believe the gears are different too. I know my stock 93 m6 is quite a bit quicker that the stock 97 m6 that the guy I bought mine off of has. He had both and he said the 93 was much quicker off the line. He kept the 97 because it was newer and had leather. He called me about a year later and wanted the 93 back. HAHA!!!

Anyway, 93s with T56 also have more aggressive transmission gearing but only come with 2.73s or 3.23s in the 10 bolt.
